Description:

Their high stability, resistance to many external stimuli, and ability to package both hydrophilic and hydrophobic compounds make these block copolymer vesicles excellen candidates for use in the medical, pharmaceutical, and environmental fields.  Ion-containing block copolymers, especially their self-assembly to give aggregates of various morphologies. Areas of research include synthesis of new block copolymers, preparation of the various morphologies, thermodynamics of self-assembly, various aspects of dynamics,behaviour on surfaces, biological applications such as drug delivery, enzyme encapsulation and bioabsorption.
